SPECIFICATION forming part of Letters Patent No. 462,208, dated October 27, 1891.

Application filed April 7, 1890. Serial No. 347,005. (No model.)

To aZZ whom it may concern:

Be it known that we, JosErE DENNIs, WIL- LIAM SHERRAN METCALEE, and JOHN AMEs SHERMAN, all of Worcester, county of Worces- 5 ter, and State of Massachusetts, have invented a new and useful Improvement in Driers for Envelope-Machines, of which the following is a specification.

So far as we know, all driers heretofore I made have consisted of what has been termed fingers mounted upon either an endless flexible belt or apron or upon the periphery or face of a drum,these fingers forming pockets into which the envelope drops or is placed,

1 5 and from which it is Withdrawn at the proper time.

Our invention consists of a drier having two plates of suitable shape located opposite each other, these plates being provided with grooves or slots, the grooves or slots of one plate being located opposite the grooves or slots in the other, the grooves being of sufficient size and proper shape to hold the edges of the envelope to be dried and the distance of the plates apart corresponding with the size of the envelope to be dried, said plates being permanently connected together and mounted on one or more shafts capable of such intermittent movement that each envelope may be automatically introduced and withdrawn at predetermined points by mechanism provided for that purpose.

In the drawings are shown two forms of our invention.

5 In Figure 1 there is shown an elevation of a drier constructed to receive envelopes moving in a line at right angles to the axis of the drier, Fig. 9 being a section on line 0000, showing the face of one of the disks of which this form of drier is made. Fig. 3 shows another form of drier constructed to receive envelopes moving in a line parallel with its axis, Fig. 4 being a section on a line y y.

In each of the figures,A represents grooves,

4 5 made preferably of the shape shown, and each sufficiently wide and sufficiently deep to hold the edge or end of the envelope to be dried. In the device shown in Figs. 1 and 2 these grooves are located opposite to each other in the two opposing disks B, mounted upon a shaft 13', their depth and width being governed by the size of the envelope for which they are to be used.

In the drier shown in Figs. 3 and 4 the grooves A are placed opposite each other in two concentric rings C 0, one set of grooves being located in the inner part of ring C and the other set of grooves being located opposite the first set in the periphery of ring 0, both rings being mounted by suitable means upon the shaft D.

In the device shown in Figs. 1 and 2 the shaft B rotates and carries the disks with it.

In the device shown in Figs. 3 and I the shaft is stationary, the drier being mounted upon a sleeve and rotated upon the shaft. In each of the devices, however, the shaft is mounted in bearings E upon the table F, the drier being conveniently located in reference to the mechanism for the delivery and withdrawal 7:: of the envelopes and being rotated by means of a paWLand-ratchet mechanism of a kind well known in envelope-machines or in some other convenient way,

Dry air for drying the envelopes may be supplied to the drier, if, thought best, and in order to make such dry air more effective the drier is best inclosed in a casing 11, of suitable shape, having an opening II, through which the envelopes may be introduced and withdrawn. In this case, however, provision should be made for the introduction of a suitable mechanism for feeding the envelope to the drier and withdrawing it therefromsuch, for example, as the recess shown at G in Figs. 8 5 3 and L. g

It is evident that the grooves A may be formed by the addition to the rings or disks of blocks, pins, or strips projecting from the opposing surfaces instead of by cutting away 0 an y portions thereof, thus practically forming opposing grooves into which the ends of the envelope may be slid.

It is obvious that while a circular drier is more convenient in most cases than one of any other shape, yet our invention may be applied to a drier of any form where it is possible to locate grooves opposite each other in plates of convenient shape located at a proper distance apart so that they shall hold the envelope and shall be moved in such a manner as to accomplish the desired end.

hat We claim as our invention is An envelope-drier consisting of two oppos ing plates permanently connected and of suitable shape, each provided with a set of grooves, each groove of one set being located opposite a corresponding groove in the other set. said plates being, suitably located and capable of an intermittent motion, and each pair of grooves being fitted to receive a freshlygurnmed envelope, in combination with mechanism, substantially as described, whereby the drier is given an intermittent motion, substantially as described.

In testimony whereof we have hereunto subscribed our names this 28th day of March, 1890.
